I would consider adding a NO_BATCH flag (which is currently triggered
using FOR UPDATE syntax) to cursorFlags.
That would be useful in some cases. And if statements with "WHERE
CURRENT OF" condition also were somehow marked client libraries could
force cursor position synchronization before executing them.
I'd expect FOR UPDATE to still disable batching even without that
NO_BATCH flag (as now), just because I can hardly see the need to
prefetch cursor (and later reposition) if a positioned UPDATE/DELETE is
expected.
